Bio 133 Exam 1 -Chapter 1-6 questions with
correct answers
gene - verified answers; segment of DNA that codes for production of a protein
allele - verified answers; a variant of a gene
DNA - verified answers; ATCG + double stranded
RNA - verified answers; AUCG + single stranded
chromosomes - verified answers; - long strand of DNA + proteins
- each has many genes
- humans have 46 chromosomes in all cells EXCEPT sex cells (23)
--> 23 from mom + 23 from dad
genome - verified answers; all genes in the cells of a particular species
genotype - verified answers; alleles an organism contains (ex: BB, Bb, bb)
phenotype - verified answers; the physical expression of the genotype (ex: BB= brown)
karyotype - verified answers; chart that displays chromosomes in size order
- able to determine sex + normalcy
, mendelian trait - verified answers; one gene causes a specific phenotype (single-gene trait)
multifactorial traits - verified answers; trait caused by more than one gene + the environment
genetic testing - verified answers; analysis of human DNA, RNA, proteins, chromosomes, or
metabolites
macromolecules - verified answers; 1. proteins
2. lipids
3. carbohydrates
4. nucleic acid
proteins - verified answers; - contain enzymes that speed up reactions
- provide structural support
- control gene expression
- prions = rogue proteins
carbohydrates - verified answers; - provide energy for cell metabolism
- provide structural support
- provide cell identity (important in immune response)
lipids - verified answers; - provide energy (dietary fats)
- main component of cell membranes
- many are hormones (chemical messengers)
nucleic acid - verified answers; - genetic material (DNA+RNA)
